SEED-COVERING ATTAGHMENT FOR LISTERS.

To all whom it may concern Beit known that we, CHARLES C. HER? MANCE and MAX REIN, citizens of the United States, and residents of Mutual, in the county of Dewey and State of Oklahoma, have invented a new and." Improved Seed-Covering Attachment for Listers, of which the following is a'description.

Our invention relates to an attachment to be applied to listers for insuring the cover ingof the seed in the lister furrow- The generalobject of our invention is to provide an attachmentadapted to be secured in position to run in therear of the mold board and provided with means to form a center line seed trench in the lister furrow, and trailing covering means so constructed and arran ed as to closethecenter seed trench by soil pressure instead of covering the seed largely by ithrowingthe dirt over the seed,

whereby the seed contact is uniform regardless of the speed of travel of the lister. With shovel or concave disk covers as now generally in use, the soil is thrown variably according to the speed of travel of the lister. The thrown soil. is more or less cloddyand direct contact between the seed and the soil is not insured. Moreover, the throwing of the soil throws also weed seed onto the planted seed.

The nature of our invention and its ad vantages and distinctivefeatures will more clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming apart of this specification, it being understood that the drawings are merely illustrative of examples of the invention.

Figure l is a side elevation of a lister equipped with our attachment;

Figure 2 is a sectional plan view on the line 2-2 Figure l;

Figure .3 is a side elevation of a modified form" of the attachment; Figuretis a plan view'of the attachment shown in Figure 8'; and g Figure 5 is a horizontal section on the line 5-5 of Figures.

The lister may be of any approved construction having a'plowbeam A and a plow-' I share B. .In theform shown in Figures 1 and 2 our attachment comprises a frame 10 having side bars, spread an increased dis tance at their rear portions 10 ,.there being suitable connections between the sides as by an arched rear cross bar 11. Supported in Application filed une so, real] s r al no. 431,717.

thefr arne 10 at the front end is an axle 12 mounting a single disk'l3 atthc medial line of the frame and mounting at the rear end an axleli on which is a pair of disks 1;"), the disks being disposed in planes at opposite sides of the line of travel oft-he front disk 13.

The rear disks are fiat and they arebevellcd at the peripheries to present a peripheral cutting edge; Means are provided to'secure the attachment atthe front end thereof in position by a vertical pivot. In the illus trated example a Ursha'ped element 16 mounted on the front axle 12 and terminates at its upper end in a spindle 17 turning in a vertical bearing 18 and a bracket 19 secured to the'standard a of the plow beam A by a transverse pivot 20. I r ,lVith the described arrangement the front wheel 13 will travel in the lister furrow 76 made by the-plowshare B and will press down a seed trench at the medial line of the furrow. The side bars of the frame 10 lie at opposite sides of the seed tube C having a seedguide D of known construction. Thus, the seed is dropped in the trench formed by the disk 13,, The rear disks 15 with their cutting edges will cutinto thesoil and with their "bevel at the cutting edges will close the seed trench over the seed'by soil. pressure by reasonof the fiat form of the rear disks 15 and their parallel arrangement at opposite sidesof the trench forming disk 13. In the form shown in Figures and 4, the frame 10*, is forkedat its rear'end and at the forwardly convergent end of the forked members, the seed tube C is accommodated, to which tube shoe D is held by a set screw 21 or the like. I In front of the seed tube is a vertical slot 22 for the shank 23 of a blade 24 functioning similarly to the disk 13, said shank being clamped by a bolt 25 passingjthro-ugh the fork 10 adjacent to slot 22. The blade 24: has a vertical slot 24? receiving the front of the shoe D, to permit vertical adjustment of the shoe and blade.

1 The arms ofthe fork 10 "are formed at their rear ends with vertical holes 26 to receive the shanks 27 of covering blades 28 of wedge shapein horizontal section, thesaid shanks 1 27 being held by set screws 29., The frame- 10 issho-wn as having an upturned front end 30 formed with afspindle 31; adapted-to be received in a bearing 18 or equivalent bearing to permit lateral turning movement 11 of the frame. p i

In both forms of the invention the trench is closed by the displacement of the laterally by direct pressure there o o? covering elements whether the covering 16- n'ients be disks or blades, so that the trench is closed by crowding ot the soil as distin guished from throwing the soil'over the seed.

A. result of the action of the attachment is that the seed in the center trench is prevented from beingwashed away on slopes durin heavy rains; In practic the outer trenches are left open to carry away surplus water. A result also is that the seed is planted "from one to two and one-halt inches deep in the center or" the lister 'lurrow bottom. Every individual seed goes to the bottom of the trench. ill thegerininating force is exerted upward. A. further rest ltis that moisture for germination is held longer. Enough soil rolls back from the mould boards for forming a inulch in the turrow.

lVe would state in conclusion that while the illustrated examples ronstitute practical embodiments of our invention. we do not limit ourselves strictly'tothe exact details,

herein illustrated, since manifestly the same can be considerably varied without departure from the spirit or the invention as defined in the appended claims.

Having thus described our invention, we claim: 7

1. A lister attachment adapted to be attached to the plow beam of a lister plow at the rear of the lister, said attachment comprising a frame mounted to swing horizontally, an element on said frame at its "forward end adapted to travel in a furrow opened by the lister plow, and a pair of covering elements at the rear of said vframe for crowding the soil on the sides of the furrow laterally inward over the pathtraveled by the firstinentioned element.

2. in atta nent for lister plows comprising a vertical bearing attached to swing vertically secured to the plow beam of the lister plow" at the rear of the lister a stub the ldlSl'rlTQllt-lODQCl element.

3. An a clunent for hster plows adapted for connection to the plow beam of the-lister plow and comprising a frame swingable both vertically and horizontally and carryin;; at the forward end an element travelling in the tlt'urrow opened by the lister plow and at the rear end a pai of crowding elements adapted to or wd the soil atthe sides of the "furrow laterally inward over the path travelled by thefirstenentioned eleinent.

l. As anew article ot manutacture, an attachment for lister plows adapted for connection to the plow'heani of the lister plow and comprising frame pivoted to swing hoth verically and horizontally and carrying at its forward end an element adapted to travel in the furrow opened by the lister plow and a pair of covering elements at its rear adapted to crowd laterally inward the soil at the sides of the tuurov: over the path travelled by the forward clement.
